LOOM.

To all whom it may concern:

Be it known that I, JOHN IV. HERBERT, a citizen of the United States,residing at Natick, in the county of Kent and State of Rhode Island,have invented a'new and useful Improvement in Looms, of which thefollowing is a specification.

This invention pertains to certain new and useful improvements in looms,and re lates more particularly to means for automatically stopping theloom when a predetermined quantity or amount of cloth has been wound onthe beam.

The object of the invention is to generally improve and simplify devicesof this type, and to provide simple, easily operated means wherebyadjustment of the parts may be effected, so that the loom will be causedto stop when different quantities of cloth have been wound on the beam.

Further and other objects of the inven tion will be later set forth.

In the drawings, Figure 1 is a fragmentary perspective view of a loom,showing the present invention applied thereto. Fig. 2 is a rear sideelevation of Fig. 1. Fig. 3 is a section taken on the line 33 of Fig. 2.Fig. 4 is a view similar to Fig. 3, but showing the parts in a differentposition, and 80 Fig. 5 is a detail fragmentary sectional view.

In the drawings the usual knock-off rod of the loom is designated 1,being journaled in brackets carried by a rail 2 of the loom 35 frame. Anarm 3 is secured by means of set screws 4: to the knock-off rod 1 and atits outer arm has a socketed member 5 adjustably secured thereto bymeans of a set screw 6. The upper face or top portion of the member 5 isformed with an integral web 8, the top edge of which is formed with aseries of steps 9, which steps are for engagement with the lower end ofa leg 10, that is secured to the outer curved end of an arm 11, thelatter being rigidly secured at its inner end toone of a pair ofvertically movable rack bars 12, which rack bars are common to looms ofa known type, in which the upper ends of the rack bars are formed withseats receiving the beam 13 of the cloth roll.

In'order to rigidly and firmly connect the leg to the arm 11, a pin 14,shown in Fig. 5 of the drawings, is secured in registering perforationsformed in the leg 10 and arm Specification of Letters Patent.

registering perforations formed in leg 10 and arm 11, and "is drawntight to firmly clamp the arms together by means'of a nut formed with alever handle 16, as depicted in Fig. 5 of the drawings.

As above stated the rack bars 12 which support the cloth beam 13 arecommon to a certain type of loom, and the rack bars in such loom areoperated by gears 17, the gears being mounted on a shaft 18, the shaftbeing surrounded by coil springs 19, which have their ends fastened tothe shaft, and also to a stationary point 20 on the loom frame, asclearly depicted in Fig. 1, of the drawings. The purpose of the coiledsprings is to take up the weight of the cloth roll, as the diameter ofthe same increases when the cloth is being Wound thereon.

It will be understood that the knock-off rod 1 has connection with theloom stopping device, and that by moving the member 5 along the lengthof the arm 3, which is carried by the knock-01f rod, that the steps 9may be adjusted so as to aline a low or high or intermediate step withthe lower end of the leg 10, which is carried by one of the rack bars12. As the cloth is wound on the beam 13 the weight thereof increases,and is taken up by the springs 19 'on the shaft 18, which bears thegears 17 the continued downward movement of the rack bars carrying theleg 10 therewith until the lower end of the leg engages with one of thesteps 9 of the arm 3, whereupon the arm in its continued downwardmovement will depress the arm 3 to rock the knock-off rod 1, therebystopping the loom.

From the above it will be seen that the adjustment may be easily andpositively effected, and that by providing a large number of steps 9various ranges of adjustments of the diameters of the cloth rolls may beobtained.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a loom in combination with vertically movingmeans for supporting the cloth beam, and the knock-off rod, an armcarried by said means and depending therefrom, a leg removably carriedby said arm, an arm secured to the knock-off rod, and a memberadjustable along the length of said last named arm and being formed withan upwzu'dly extending web, the top edge of which web is formed with aseries of steps I to engage with the lower end of said leg.
